Abstract
The present invention relates to a shade structure for a candle, and in particular, the shade structure comprising a container body for containing a candle, a shade body with a center air hole and detachably mounted onto the circumferential edge of the container body, and a covering plate having a center hole aligned with the center air hole of the shade body. The shade body is provided with a plurality of auxiliary openings which are corresponding to a plurality of through holes provided on the upper edge of the covering plate. The covering plate can be rotated with respect to the shade body such that the through holes align with the auxiliary openings and this will control convection of air within the container body. The temperature within the container body is thus regulated by adjusting the covering plate with respect to the shade body.
Description
BACKGROUND OF THE INVENTION
a) Technical Field of the Invention
The present invention relates to a structure of a shade for a candle, and in particular, a shade body and a covering plate, both provided with a plurality of auxiliary openings and a plurality of through holes respectively. The covering plate can be rotated with respect to the shade body until the openings and the holes are aligned so that state of burning candle within the container body can be regulated.
b) Description of the Prior Art
FIGS. 5
shows a conventional candle shade having a container body
30
with an open end having a stepped ring
31
to accommodate a shade body
40
. This structure prevents the blowing of strong wind which will extinguish the burning candle within the container body.
This conventional structure allows the burning candle to burn in a very stable manner and the hot air of the burning candle is kept within the container body
30
. This structure is effective in lighting the wick of the candle during winter. However, in such conventional design, a center opening
32
is provided to the shade body
40
so that the flame of the candle can reach outside the container body, and a plurality of apertures
33
are provided along the circumferential edge of the shade body
40
. As shown in
FIG. 6
, hot air rises and the hot air is dispersed out via the center opening
32
. In this case, the speed of dispersion of hot air is slow. In summer, due to the hot air which is accumulated at the top portion of the container body
30
, the top part of the candle will be melted and at this instance, the wick
34
of the candle will become longer and the flame of the burning becomes larger. As shown in
FIG. 7
, the flame will move in accordance with the convection of air. As a result, the flame may be blown so close to the container body
30
which will damage the wall of the container body
30
. In addition, the melted wax may flow out of the container body
30
, which further causes a danger to the user.
SUMMARY OF THE INVENTION
To save the aforementioned problems, it is an object of the present invention to provide a structure of a shade for a candle, wherein the through holes provided on the covering plate can be adjusted to correspond with the auxiliary openings of the shade body so as to provide an optimum size of the opening for air passage, which in turn, provide convection air for the burning candle, thereby the effectiveness of candle burning is obtained.
Yet another object of the present invention is to provide a structure of a shade for a candle, wherein a plurality of protruded decorative discs are provided along the edge of the covering plate, adjacent to the through holes, thereby an aesthetic appearance for a candle shade is thus obtained.
Yet another object of the invention is to provide a structure of shade for a candle which is comparatively compact and light in weight.
Other objects, features and advantages of the invention will be apparent from the following description when read with reference to the accompanying drawings.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT
FIGS. 1
to
3
show a structure of a shade for a candle in accordance with the present invention. The shade structure comprises a container body
10
having an open end, a shade body
20
, and a covering plate
21
. The open end of the container body
10
, along the circumferential edge thereof is provided with a recessed stepped ring
11
, which is adaptable to the circumferential edge of the shade body
20
, which is detachably mounted onto the top of the open end. In accordance with the present invention, the covering plate
21
is rotatably and detachably mounted onto the shade body
20
. The shade body
20
has a curved region at the center thereof, containing a plurality of auxiliary openings
24
and a center air hole
22
is provided to the center of the shade body
20
. A plurality of apertures
23
are provided along the top circumferential edge of the shade body
20
to allow convection flow of air into the container body
10
. In accordance with the present invention, the shape of the auxiliary openings
24
can be circular, oval, rectangular, square or rhombic shape. The top of the covering plate
21
is provided with a plurality of through holes
251
, which can be rotatably adjusted to corresponding to the auxiliary openings
24
of the shade body
20
by rotating the covering plate
21
with respect to the shade body
20
. A plurality of protruded decorative discs
25
are provided on the covering plate
21
, adjacent to the through holes
251
of the covering plate
21
. The decorative discs
25
provide the entire shade structure with an aesthetic appearance. In order to stably mount the shade body
20
onto the stepped ring
11
, a plurality of protrusions
26
are provided to the bottom circumferential edge of the shade body
20
.
In order to moveably rotate the covering plate
21
with respect to the shade body
20
, the user can push the decorative discs
25
until the through holes
251
and the auxiliary openings
24
overlap or correspond with each other. Based on burning requirements, the size of the openings
24
is adjusted by adjusting/rotating the covering plate
21
.
As shown in
FIG. 4
, when the room temperature is high, the heat within the container body
10
may not be easily dispersed to the outside. For this instance, the covering plate
21
is appropriately moved with respect to the shade body
20
such that the protruded decorative discs
25
(or the through holes
251
) are corresponding to the auxiliary openings
24
of the shade body
20
, forming a through opening. This will allow hot air within the container body
10
to disperse through the air holes
22
and the auxiliary openings
24
. Thus, the temperature within the container body
10
is effectively regulated, and this assures that the temperature at the top part of the container body
10
is not high enough to melt the candle. During winter, the protruded discs
25
are moved to a position in between two auxiliary openings
24
so that the container body
10
has a comparatively larger sealed space to retain the heat.
In accordance with the present invention, a recessed circular slot
27
is provided at the lower section of the curved surface of the shade body
20
, such that the lower circumferential edge of the covering plate
21
can be rotatably and detachably mounted.
While the preferred embodiment of a shade for a candle is illustrated, this embodiment is presented by way of example only and not in a limiting sense. The invention in brief comprises all the embodiments and modifications coming within the scope and spirit of the following claims.
